How to use the online alarm clock
Before handing the kiosk over to the next person, set the alarm for 2:23 pm so they have a clear cue to begin preparing for the lunchtime rush. That leaves a useful stretch before 3:00 pm for checking the float, restocking quick-selling items and explaining anything unfinished without making the change of shift feel hurried.
During a kiosk handover, the alarm can appear to be set correctly while its sound has quietly been routed to headphones left beside the computer. Check the audio output and play a brief test sound before stepping away, then leave the volume high enough to be heard over customers and equipment. Because the alarm relies on the browser continuing to run, it cannot safeguard the kiosk opening if the computer goes to sleep or the browser session ends.
A change of staff around midday can also change how the space feels: someone arriving from outside may be warm, while the person leaving has grown used to the air conditioning. Mention the current setting during the handover and keep water somewhere accessible, rather than turning the cooling sharply up or down. At 2:23 pm, direct sun through a kiosk window can add noticeable heat, so closing a blind or moving stock out of the sun may make the run towards 3:00 pm more comfortable.
Common questions
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 2:23 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
